    Using Weld to inject new JMS 2 API

    Jeff Mesnil Master

      Hi,

       

      I'm adding support for JMS 2.0 in WildFly and one of its new features is an injectable JMSContext object[1].

       

      I'm following the Weld documentation to provide a portable extension[2] to HornetQ so that its JMSContext can be injected.

      However this fails because the call

       

      final AnnotatedType<JMSContext> at = bm.createAnnotatedType(JMSContext.class);

      final InjectionTarget<JMSContext> it = bm.createInjectionTarget(at);

       

      throws an exception:

       

      org.jboss.weld.exceptions.DefinitionException: WELD-001508 Cannot create an InjectionTarget from public abstract interface class javax.jms.JMSContext as it is an interface

                at org.jboss.weld.manager.SimpleInjectionTarget.&lt;init&gt;(SimpleInjectionTarget.java:65)

                at org.jboss.weld.manager.BeanManagerImpl.createInjectionTarget(BeanManagerImpl.java:922)

                at org.hornetq.jms.cdi.HornetQCDIExtension.afterBeanDiscovery(HornetQCDIExtension.java:55

        ...

       

      I tried using a producer method[3] to create a HornetQJMSContext (the HornetQ implementation of the JMSContext interface) but that does not seem to be picked up.

       

      I'm sure I am missing something pretty obvious but how can I chose the HornetQ implemenation of JMSContext when I create a injection target for the JMSContext interface? Should I use alternatives for that (I'm not sure to understand how they'd help)?

       

      Any links to the right section to RTFM would be helpful

       

      thanks,

      jeff
